These are tiny, unresponsive dots that appear on the screen, causing a distraction and negatively impacting the viewing experience. Understanding the causes of dead pixels can help users prevent and address this problem effectively.

Unfortunately, dead pixels cannot be fixed. Once a pixel is dead, it remains non-functional. However, there are some techniques that can minimize their visibility.
